The article deals with the problem of the quality of graphical user interfaces used for various software products. The indicators for evaluating the quality of interfaces are analyzed. A formalized approach to evaluating the speed of information search and functional objects is formulated. An algorithm for evaluating the speed of information search and functional elements is proposed, which allows automating the process of evaluating and comparative analysis of interfaces of various programs.

Current development of Armed Forces of the Russian Federation is determined by advancing information technologies. The role of information support in the Navy is constantly growing and is crucial in military decision-making. The article deals with the conceptual approach to the integrated automation of situation awareness in the Navy’s computer-aided control system in order to enhance forces/troops management by providing the force command and military authority officers/ operators with analytical data obtained through acquisition and processing of situation information. For automation upgrade and effective management, the mathematical models of data processing represented by linear differential firstdegree equations are given. These models describe the kinetics of various generated information resources and show analytical solutions of the volume of output information resources versus the volume of initial data and conversion rate.

A closed-loop sampled-data system with short pulses with arbitrary modulation is studied. The sufficient condition of asymptotic stability in large of the system equilibrium state is obtained with the help of Lyapunov function for the nonlinear continuous part of he system. The estimate of the obtained condition and examples of its application are presented.
